Create New Binary Variable From String Variable

KNIME Analytics Platform
#1

I have a data set with a String column with a fixed set of entries.

For the sake of example, suppose the values in this Column are:
yellow, blue, green, orange, red, purple, black, white

I want to create a new variable (appended to the dataset) that is derived from this variable that is essentially:
= 1 if String Column in (yellow, blue, red)
= 0 otherwise

I intend to use this new variable as a response variable in a binary model.

I’m unsure of how to do this in KNIME. Any help would be appreciated.
Thank you.

The Rule Engine node will do what you want. See https://nodepit.com/node/org.knime.base.node.rules.engine.RuleEngineNodeFactory for details and examples.
